CAPM-3o Carrier Frequency Pickup Module

Installation & Technical Guide

Installation:

• Ensure that the flow meter sensor cavity is free of debris prior to installation.

• Remove the lid from the CAPM-3o, use the 2 inner screws to attach the sensor to the meter and replace the lid.

Wiring should be installed by a qualified instrumentation technician.

Some basic installation guidelines are reviewed overleaf.

Description:

The CAPM-3o is a UL approved, intrinsically safe pickup sensor for use in Class 1, Div. 1 locations. The output

signal is a frequency proportional to flow in a square wave voltage form of approximate amplitude: Supply –

1.5V. The sensor must be installed with an intrinsic safety barrier in accordance with the guidelines detailed in

document # CAP2902 – CAPM INSTALLATION IN HAZARDOUS AREA. Recommended barriers such as

Pepperl & Fuchs Z787 (12-28V) are available from AW Gear Meters.

The output is a sourcing open collector transistor (NPN Type).

An NPN sinking type is available and is designated as CAPM-3i.
